Abstract
A multiple-disc filter body (10) for separating solid particles from a fluid flowing through the filter body from its inlet side to its outlet side, comprises a stack of filter discs (14) in which the side faces (14a,14b) of each pair of adjacent discs (14) are formed with ribs (42a,b,c) of at least two different heights such as to define filtering passageways of a larger size on the inlet side of the filter stack and filtering passageways of a smaller size on the outlet side of the filter stack in series with the larger-size filtering passageways, whereby coarse particles are first separated by the fluid in the larger size filtering passageways, and then finer particles are separated from the fluid in the smaller size filtering passageways.
